PC: Time Trial mod problem after the patch

Hello everybody.
After install the second patch for the game when I play the Time Trial mode I have the following problem: after make a few laps when I return to the pits and I want to go into the monitor, let's just say for adjust my setup, the game freezes and crashes to desktop.

Only happens with Time Trial mode, not with Grand Prix or Career mode.
Any ideas?.
Thanks in advance.
